The wires were $75 from Part Source after tax,so they were well worth the money.

As for the ticking noise, when my car ticks it means the oil is low. One additive I added to my car which stops the ticking is Rizlone Oil Additive for stopping oil burning. The Rizlone is REALLY thick and coats the overhead cam which in turn stops the ticking. You can buy it at Canadian Tire and it is very cheap.
